dcnt ol Bruggen, near Gallon, S

land, have nvented a no and u: 'ul

of Prodm g lhaintitch, oi which the lollov-Jing a specification.

V ates to such a method of invention 2 producing chaiu-- itches .ilar, or nearly similar, on hoth sides oi the material. This stitch is to he used principally the cmhroidering of curtains or similartiss ues,'-.ihic.l.i. are desired to alike on both sides.

y icthod is illustrated stop hr step in Figures 18 of the accompanying drawings, but the implements used are onl shown diagranunatically. Figs. 1, 3, 5 and 7 sho the stitch in the longitudinal direction of the seam and Figs. 2, l, 6 and 8 sho t is corresponding positions in the transverse direction of the seam.

For carrying out my method i use a hohlgin (I turning on a vertical axis and consisting of a cylindrical hex "with an opening a provided ccccntrically at the upper edge for letting out the thread. in the direction of the axis of the hohh-in (L there moves up and do; n, ahove the same, a hool ied needle 0. in the transverse direction moves horizont a tonguedneedle 6 ahove the center of th iohhin o to and fro, whose hoolc is nroviiiled ith a closing tongue 6. (floo above the needle 6 is a needle-platef ol the usual kind which serves as a SUpPOl'tto the material (Z to he oin- ,roidered l 'hen a stitch is to he made the thread 2) coinin g out of the hohhin a (Figs. 1 and 2) drawn v'ith the hooked-needle 0 through tl material (1. '5 he tongued-needlc has grassed through the loop pres ously formed by it (Fig. 2) towarril the left. Now the material (Z on the needle-plate f is advanced by the length of a stitch. The hooked-needle 0 passes through the material downward (Figs.

0 and 4-) and holds fast with its shank the time seized loop of the thread b after the same has heen drawn up. The thread 5 passing from the hohhin, in consequence of the rotation of the same, holowr the tongue '.-needle c, is, at the l the latter and drawn hack (lf' ig. toi'.'-- l the right. By the further rotation of the l'rohhin a the thread b is put into the h: r. of the lowered needle (3 (Figs. 5 and 6) and the latter commences to move u Ward again, hile the tongued-needle c continues in its 1216"? .nient (Fig. 6) to- W2. d the right, so that the thread seized hy it is drawn along h" it and the loop previ ously formed h it, and not lying on it, is brushed oil from by this movement. Now the needle 6 moves further upward as far as possible (Figs. 7 and S) and draws in this Way the thread through the material, While the to1igue l-* erllo draws the loop previously seiz d 1/, i ike entirely through the loo pped from it. The material at l5 ng on the needle plate/f is no -.1 moved for Ward agair the length of a stitch and the process repeated.

aving 110W dr crihed my invention what 1 claim and desirr to protect by Letters Patent is:

A method oi" roducing by means of one thread. a stitch .o ing at both sides of the material a form like a well known chain stitch, consisting in drawing the thread from one side tlU'O" 1 the material thereby forming a loop at t i. other side. of the material, leaving at the same time a loop at the side from "which the thread drawn through the material, keeping hoth loops in. position by suitable means, transporting the material the length of a stitch, and drasing again the thread through both loops and. the material.

in -i'vitness whereof .i have hereunto set my hand in the presence of two "Vltll-BSSGS.
